Buck on homosexuality: 'You have a choice'

During a debate on 'Meet the Press' Sunday, Colorado Republican Senate candidate Ken Buck said he believes that being gay is a choice but that, "like alcoholism," there are also biological factors that contribute to homosexuality.

Asked by host David Gregory if he thinks being gay is a choice, Buck replied, "I do."

"You can choose who your partner is," Buck added. "I think that birth has an influence, like alcoholism and some other things ... But I think that, basically, you have a choice."

After the debate, Buck clarified that he thinks there is "some element of predisposition" in homosexuality. He noted that he mentioned alcoholism as an example of another behavior that can be influenced by genetic factors.

"I wasn't talking about being gay as a disease," Buck said. "I don't think that at all."
